Man, that's nuts!
Imagine the panick of the guy on the boat a few down which was occupied at the time.

I was with my friend in his Bayliner Capri filling up at the fuel dock. His bayliner had back fired earlier in the week and I told him to at least turn on the blower fan to clear the engine of fume's or at least open it. It backfired and caught on fire and was fully "involved" pretty dang fast. Lucky that it was untied and sort pushed off from the dock when it happened and I'm glad that it was a bow rider gave me a good exit point. Dang lucky cause a burning boat if tied to a fuel dock could have been real bad!!!!!
